SURFACING LUMBER.

Application filed October 29, 1925. Serial No. 65,705.

The invention relates to surfacing lumber as described in the present specification and illustrated in the accompanying drawings which form part of the same.

The invention consists essentially of the novel features of construction pointed out broadly and specifically in the claim for novelty following a description in detail of an acceptable form of the invention.

The process for producing lumber of the kind herein disclosed is described and claimed in applicants copending application Serial No. 65,706.

The objects of the invention are to produce a board for floors and other surfaces that will prove impervious to moisture by a filling on the inner side and by the surface finishing on the outer side; to effect a beautiful finish on exposed surfaces; to avoid warping, couping and heaving, and lengthen the life of the boarding; to effect these purposes in an economical manner; and generally,to provide durable and efficient boarding for all kinds of surfacing.

In the drawings, Figure 1 is a plan view of a board showing its finished side.

Figure 2 is a planview of a board showing its unfinished side treated.

Figure3 is an enlarged cross sectional View showing a treated flooring. v

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, the board 10 is finished or milled on the side 11 and unfinished or rough on the side 12, and on the side 12 the filler 13 is introduced by pressure and generally applied over all the surface, so that all the pores and other interstices are filled and capped forming a positive barrier to the penetration of moisture into the board.

The face side 11 is treated usually after the laying of the floor with fillers, oils, varnishes or polishes, or in some cases paints, thereby insuring non-penetration of the flooring from below or above and the elimination of all tendency towards warping, couping or heaving, as well as effecting av barrier to the encroachment of vermin and all destructive agents.

The substance employed is a fluid mixture of denatured alcohol, turpentine and copal and unfinished surfaces, said lumber containing a'mixture of denatured alcohol and turpentine and copal gum extending inwardly from a coating of the same in its consistent state on the unfinished surface of the board.
